Izinhlobo (zezinyoni):I-Crane enemiqhele ebomvu (i-Grus japonensis)
Isifinyezo:
Izindlela zokulondoloza eziphumelelayo zincike kakhulu olwazini lokukhethwa kwezindawo zokuhlala zezinhlobo eziqondiwe. Kuncane okwaziwayo ngezici zesikali kanye nesigqi sesikhathi sokukhethwa kwezindawo zokuhlala ze-crane ebomvu esengozini yokuqothulwa, okunciphisa ukulondolozwa kwendawo yokuhlala. Lapha, ama-crane amabili abomvu alandelwa nge-Global position system (GPS) iminyaka emibili e-Yancheng National Nature Reserve (YNNR). Kwasungulwa indlela yezikali eziningi ukuze kutholakale iphethini yendawo yokukhethwa kwendawo yokuhlala yama-crane abomvu. Imiphumela yembule ukuthi ama-crane abomvu akhetha ukukhetha ama-mariqueter e-Scirpus, amachibi, i-Suaeda salsa, kanye ne-Phragmites australis, futhi agweme i-Spartina alterniflora. Esikhathini ngasinye sonyaka, isilinganiso sokukhethwa kwendawo yokuhlala sama-mariqueter e-Scirpus kanye namachibi sasiphezulu kakhulu emini nasebusuku, ngokulandelana. Ukuhlaziywa okwengeziwe kwezinga eliningi kubonise ukuthi ukumbozwa kwamaphesenti e-Scirpus mariqueter esikalini esingamamitha angu-200 kuya kwangu-500 kwakuyisibikezeli esibaluleke kakhulu kuzo zonke izinhlobo zokukhetha izindawo zokuhlala, kugcizelela ukubaluleka kokubuyisela indawo enkulu yendawo yokuhlala ye-Scirpus mariqueter yokubuyiselwa kwenani le-crane elibomvu. Ngaphezu kwalokho, ezinye izinto eziguquguqukayo zithinta ukukhethwa kwendawo yokuhlala ezikalini ezahlukene, futhi iminikelo yazo iyahlukahluka ngokwesigqi sonyaka kanye nesijikelezo se-circadian. Ngaphezu kwalokho, ukufaneleka kwendawo yokuhlala kwahlelwa ukuze kuhlinzekwe isisekelo esiqondile sokuphathwa kwendawo yokuhlala. Indawo efanele yendawo yokuhlala yasemini nasebusuku yayibalelwa ku-5.4%–19.0% kanye no-4.6%–10.2% wendawo yocwaningo, ngokulandelana, okubonisa ukuphuthuma kokubuyiselwa. Ucwaningo luqokomise isigqi sesilinganiso kanye nesesikhathi sokukhethwa kwendawo yokuhlala yezinhlobo ezahlukene ezisengozini yokuqothulwa ezincike ezindaweni ezincane zokuhlala. Indlela ephakanyisiwe yezikali eziningi isebenza ekubuyiselweni nasekuphathweni kwezindawo zokuhlala zezinhlobo ezahlukene ezisengozini yokuqothulwa.
